Well some people may not want to use any additional lights at all to color their objects. Or some people may need a little bit extra coloring from the surrounding areas. This script will shoot a ray down and get the lightmap pixel value directly underneath the player. Very useful for the player view guns which is what the script is setup for (that’s why the player variable is an array, my gun and arms are 2 different models).
One thing to note: You have to enable Read/Write on the Lightmap textures for this to work!
Hope this helps someone.
